Rotation of Asymmetric Top01:11

Rotation of Asymmetric Top

1.5K
By definition, a spherically symmetric body has the same moment of inertia about any axis passing through its center of mass. This situation changes if there is no spherical symmetry. Since most rigid bodies are not spherically symmetric, these require special treatment.
The relationship between the angular momentum of any rigid body and its angular velocity, both of which are vectors, involves the moment of inertia. The moment of inertia is a scalar quantity only for spherically symmetric...

Asymmetric Lipid Bilayer

9.8K
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Directing Effect of Substituents: meta-Directing Groups

5.9K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Sound Intensity00:58

Sound Intensity

4.8K
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the...

Area of Science:

  • Photonics and optical engineering
  • Materials science
  • Nonlinear optics

Background:

  • Asymmetric wavefront shaping is crucial for advanced photonic functionalities like unidirectional transmission and nonreciprocal light control.
  • Achieving these functionalities in passive nonlinear metasurfaces is challenging due to trade-offs in nonlinear efficiency, phase modulation, and directional asymmetry, especially on low-index substrates.

Purpose of the Study:

  • To propose and demonstrate a novel meta-lens design for effective asymmetric wavefront shaping.
  • To overcome the limitations of existing metasurfaces by integrating local and nonlocal resonances.
  • To achieve strong directional response and high nonlinear efficiency on low-index substrates.

Main Methods:

  • A hybrid meta-lens design integrating local Mie-type resonances with nonlocal quasi-bound states in the continuum.
  • Utilizing substrate-induced asymmetry without additional layers.
  • Experimental characterization of directional focusing at fundamental, second, and third harmonic wavelengths.

Main Results:

  • The proposed meta-lens exhibits a strong directional response originating from silica substrate-induced asymmetries.
  • High nonlinear efficiency and robust phase modulation are preserved.
  • A maximum forward-to-backward power ratio exceeding 10 dB was experimentally demonstrated for directional focusing.

Conclusions:

  • The developed hybrid meta-lens effectively achieves asymmetric wavefront shaping and nonreciprocal light control.
  • This design offers a pathway to overcome existing trade-offs in metasurface functionalities.
  • The work presents new opportunities for applications in nonreciprocal LIDAR and optical computing.
